serial No. 352,978.

citizen of the United States, and a resident of' the city of Reading, inthe county of Berks and State of Pennsylvania, have invented certain newand useful Improvements in Carbureters for Explosive-Engines, of whichthe following is a specification. ,k l

My invention relates particularly to carbureters adapted for motor cycleuse, and it consists in certain improvements in construction hereinafterfully described in connection with the accompanying drawings and thenovel features of which are specifically pointed out in the claim. V

The drawing is a artly sectional elevation of a carbureter emfiodylng myinvention in preferred form.

An ordinary spraying device for gasolene or other hydrocarbon liquid, isindicated at 5, located in a central tube 6 of the carbureter andcommunicating through suitable conduits 7, 8, with a gasolene chamber 9.As shown this central tube 6 rises from a perforated or spoked plate 10which screws into the lower end of the mixing chamber cylinder hereafterdescribed, and it is loosely surrounded by a partition ring 11 carriedby said late 10. This partition rin forms an annu ar outer air-chamber12 an an annular inner air-chamber 13 both communicating with a lowerair-inlet lchamber 14 which is carried by a depending extension 15 ofthecentral tube 6.

The mixing chamber cylinder as shown is formed by a lower main ortion 20and an e former of which is rovided witll a vertically movablecylindrlcal cut-ofi valve 22 in addition to the sprayer 5 and artitionring 11 already mentloned, while t e latter is provided with a rotarycylindrical throttle valve 23 arranged to regulate the volume of fuelgas discharged side outlet 24 therefrom, the particular construction`and coperative arrangement of these parts-as shown, beine' fullydescribed and claimed in my original application, Serial No. 334,368,filed September 13, 1906, of which the present application is adivision.

The gasolene chamber 9, as shown, is an annular chamber surrounding themixing cylinder 20 and formedintegral therewith, the separately formedupper cylindrical uportion 21 being fastened to the lower cylindricalportion 20 bymeans of a suitably secured ange 45 arranged to cover saidgasolene chamber.

The su ply of gasolene to the chamber 9 is controlla as usual by aneedle valve 50. This valve as shown is mounted in a vertical conduit51, connected to a sup ly tube 52 and communicating at 53 with t echamber 9. To pro-vide for nicely adjusting this valve its point isseated ina ring 54 which is adjustable vertically 'n a screw-threadedportion of the conduit 51, while the upper portion of its stem is guidedin a screw-cap 55 and its vertical lift is regulated by an adjustingscrew 56 as indicated. To provide for the automatic o l eninfr andclosing of the valve as required empnloiy7 a lever 60 pivotedintermediately at 61 and aving its short end 62 engaging the collaredstem of the valve While lts semi-circular inner portion is carried halfway around the mixing cylinder 2O and has its ends 63 arranged tocontact with an annular float 64 in the gasolene chamber 9 so vas to belifted bv the latter when said chamber is pro erly filled, and therebyclosing the needle va ve which is normally held open by said lever.

What I claim is y In a carbureter a hydrocarbon chamber with a floattherein, an interiorly screwthreaded supply conduit having a lateraloutlet to said hydrocarbon chamber and a supply tube connecting end, anexterior y screw-threaded valve-seat ring adjustably located within saidconduit below said outlet, a valve seating on said adjustable ring andhaving a collared stem extending above said outlet, any adjustable stopto limit the opening movement of said valve, and a pivoted leverextending through said outlet, to the valve stem, and operated by saidfloat to automatically close said valve, substantially as set forth.

In testimony whereof, I aiiix my signature, in the presence of twowitnesses.

LOUIS P. FOSNOT.
